I just saw a guy shove loads of chocolate bars and candy into a big black bag, get two beers. I got curious cause usually people don’t put stuff they intend to buy into bags.
Then he proceeds to checkout but only pays for the beers, not a single beep from the sensors. Are they only meant to detect certain items or did the homeless guy have something to disrupt the sensors?

Rfid’s work on radio frequencies. Have a bag with metal threads interwoven, making a Faraday cage, and the detectors should be bypassed.
